18 Claims.

This invention relates to weatherstrips, particularly metal weather strips for Windows equipped with sliding sashes. It has for its principal objects to pro-vide an eicient and durable weatherstrip of simple and economical construction which can be readily applied to the window without material alteration thereof; which will prevent rattling of the sash in the frame; which will automatically accommodate itself to shrinking and swelling of the sash and frame and, at the same time, maintain a weatherproof joint therebetween and insure an easy movement oi the sash; which will permit removal of the sash from the frame without removing the sash strip from the sash or the frame strip from the frame; and

which will permit the frame strip to be mounted in and dismounted from the frame with the parting bead as a unit.

The invention consists in the weatherstrip and 2U in the construction, combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawing, which forms part of this specication and wherein like symbols referto like parts Wherever they occur,

Fig. l is a fragmentary horizontal section through one side of the frame and the adjacent portion of the sash of a double hung Window equipped with a metal weatherstrip embodying my invention,

3U Fig. 2 is a similar section, showing the weatherstrip on an enlarged scale,

Fig. 3 is a view looking at the lower portion of the parting bead side of the sash strip; and

Fig. 4 is a horizontal cross-section similar to Fig. 2 showing a metal weatherstrip of modified form.

Figs. 1, 2, and 3 of the accompanying drawing show the invention in connection with a double hung window construction comprising a window frame including a pulley stile or jamb A, a stop B, and a parting strip or stop C mounted in a groove C provided therefore in said pulley stile or jamb, all arranged to form a vertical slideway for a closure member or sash D. The joint between the vertical meeting edges of the pulley stile A and the sash D of said window is rendered weatherproof and dustproof by means of a weatherstrip comprising cooperating strips E and F mounted on the parting strip C and the sash D, respectively.

The frame or stile member E of the weatherstrip is made of a strip of resilient metal that is bent or folded lengthwise along one line to form a side marginal flange I, which has a hemmed free marginal edge 2, a portion 3 disposed substantially at right angles to said iiange, an outstanding longitudinal rib i on said flange where it joins the portion 3, and a resilient hollow bead portion 5 that forms a connecting hinge between the portion 3 and a portion 6 that extends in the direction of the marginal flange l at a diverging or oblique angle tol the portion 3 and then parallel therewith to a point short of the flange I where it joins the other side marginal flange '1, which is doubled back over the portion 6 to form a groove 8 and terminates in a hemmed free marginal edge. The sash member F of the weatherstrip is also made of a strip cf resilient metal that is longitudinally bent or folded to form a portion 9, a flange iii at one margin of the portion 3 that is provided with a hemmed free marginal edge Il and is disposed substantially parallel with but spaced from the portion 9 to form a groove I2 on one side thereof, a portion I3 extending from the other margin of the portion 9 substantially at right angles thereto on the other side thereof, and a resilient flange Id extending from the free margin of the portion i3 on the side thereof remote from the portion Si to a point beyond the other margin of the portion I3 where it terminates in a free marginal portion I5 that is curved in the direction of the groove I2.

The frame member E is mounted in the frame of the window with its marginal flange I alongside of the sash opposing face of the parting strip C, with its portion 3 alongside of the sash opposing face oi the pulley stile A and with its groove 8 disposed alongside of the stile opposing edge of the sash D and opening toward the side of said sash remote from said parting strip. The frame strip E is secured to the parting strip C along the hemmed edge 2 oi its flange I by tacks or other suitable fasteners I6; and the rib 4 on the opposite edge of said iiange ts in a longitudinal groove I'l provided therefor in the sash opposing face oi the parting strip C in the plane of the sash opposing face of said pulley stile A. The sash strip F has its portion i3 disposed alongside of the parting bead opposing face of the sash D and secured thereto along the margin remote from the portion 9 by tacks or other suitable fasteners I8; and the portion 9 of said strip is disposed alongside of the stile opposing face of said sash with the hemmed marginal ange I0, which forms one wall of the groove I2, tting Within the groove 8 in the frame strip E. When the frame and sash strips are thus engaged, the curved free marginal edge I5 of the marginal iiange I4 of the sash strip resiliently engages the CTI CJD

f the two strips in engagement.

frame strip along the line where it is bent to form the groove At the lower end of the sash strip F, the resilient frame strip engaging ange M- thereof has its free marginal portion cut away, as at it at its lower end so as to permit said flange to clear the grooved lower end of the frame stripwhen the sash is raised to its full height, thereby permitting engagement and disengagement of-the interlocked ends cf the two strips in a horizontal direction instead of a longitudinal direction. As shown in Fig. 3, the edge of the sash strip flange lll is cut at an oblique angle so as to guide the sash strip into engagement with the frame strip.

The foregoing weatherstrip has numerous advantages. The marginal flange lil which forms one wall of the groove i2 in the sash strip F, fits within the groove 3 in the framerstrip E and the marginal ange l, which forms one wall of the frame strip groove, nts within the sash strip groove thus giving a double, slidably interloclred engagement between the two strips. The marginal flange lli oi the sash strip E bears resiliently against the frame strip where it is bent to form the sash strip receiving groove 8 and thus holdsthe two strips in slidably interlocked engagement and resists movement of the sash between the stop B and parting bead or stop C, thereby preventing rattling of the sash in the i'rame. In the event the sash warps, the portions i and i3 or" the sash strip will conform to the Warp of the sash and the flange i@ of said sash member will remain straight and in full line contact with the frame strip and thus maintain The curved edge I5 of the flange lli of the sash strip also tends to pull the frame strip away from the frame as the sash shrinks, thereby relieving the strain on the interlocking portions ci the strips that is liable to cause leakage or air therebetween. The beveling olf of the lower end of the resilient flange is of the sash strips permits the two strips to be quickly and easily engaged and disengaged in the raised position oi the sash without removing the sash strip from the sash or the frame strip from the parting bead; and the mounting of the frame strip on the parting bead permits these two members to be attached to and removed rom the frame as a unit. The rib and groove engagement between the frame strip and parting bead tends to prevent passage of air around the parting bead; and, if the sash shrinkage is enough to pull the hollow bead portion 5 of the frame strip away from the pulley stile, the portion 3 carrying said bead will bend at therib i and swing the grooved sash strip engaging portion thereof in the direction of the parting strip, thus forcing the sash in the direction of said parting strip and preventing increased clearance therebetween.

In the modiiied construction shown in Fig. 3, the weatherstrip comprises a single frame strip E that is bent to :form a marginal flange la having a hemmed margin 2a secured by tacks ita to the sash opposing face of the parting strip C and a ribbed margin lla, that fits in the groove il in said face of said parting strip, and a portion 3a that extends from said ribbed margin do. to the marginal ange la alongside or" the pulley stile A and is provided with a hollow bead 5a, that forms a hinge connection between said portion and the other marginal or sealing iiange 'la of said strip that extends in the direction of the marginal flange la at a diverging oblique angle to the portion 3a and terminates at its free margin in a reversely inclined hemmed portion io that bears resiliently against the stile opposing face of the sash D. This construction forms a simple and eiiicient one-piece weatherstrip that prevents passage of air around the parting bead groove and can be removed and properly replaced with the parting bead without removing the securing nails ior said strip and damaging the latter.

Obviously, the invention is not limited to use with the window construction shown and described.
